T/CAAMTB 177—2023 was published on 29 December 2023 and implemented on 1 January 2024. Although its Chinese title refers broadly to traction-battery product dimensions, the registered scope specifically recommends cell dimensions and excludes module and system dimensions. That boundary is useful for international readers and warrants separate indexing from the 2019 module-dimension standard. A CABIA workshop announcement from 2023 provides historical context for work on battery dimensions. The workshop record and the final standard registration are separate evidence sources, and this entry does not infer technical interchangeability beyond the registered scope.
